The ChemGrout CG-550 Thin Mix series includes both skid and trailer mounted grouting equipment. The Thin Mix unit is designed to mix and pump neat cements, bentonites, cement/bentonites, and lightly sanded grout mixes. These units feature a 45 gallon (170 liters) mixing tank, a 10 gallon (38 liters) holding hopper and a 10 GPM (38 LPM) progressive cavity grout pump. The balanced design of this grout plant allows continuous mixing and pumping, while the hopper is feeding the pump another batch can be mixed. The mix tank is equipped with baffles, bag breakers and variable speed high-efficiency paddles that provide rapid mixing. The tank outlet valve is a large slide gate that allows the materials to fall easily into the pump hopper. The grout pump is a variable speed, positive displacement, progressive cavity, rotor-stator pump. Operator controls are centrally located for efficient production. All components are easily accessible for operating, cleaning, and maintenance. The trailer mounted unit is road and job site ready equipped with leaf springs, lights and a working platform.
